The title diastereomeric salt, formed between 2-amino-1,2-di-phenyl-ethanol (ADE) and aspartic acid (ASP), CHNO·CHNO·HO, crystallizes as a monohydrate. The 1,2-di-phenyl-ethyl group in the cation has a conformation, and the aspartic acid anion is in the zwitterionic form. In the crystal, the ASP anions are linked N-H⋯O hydrogen bonds to form a 2 helix along the -axis direction. The helices are linked by the ADE cations O-H⋯O and N-H⋯O hydrogen bonds, forming layers parallel to the plane. There are channels in the layers that are occupied by water mol-ecules, which link to both the anions and cations O-H⋯O and N-H⋯O hydrogen bonds. There are also C-H⋯O and C-H⋯π inter-actions present within the layers.
由2-氨基-1,2-二苯基乙醇（ADE）和天冬氨酸（ASP）形成的非对映异构盐CHNO·CHNO·HO以一水合物形式结晶。阳离子中的1,2-二苯基乙基具有一种构象，天冬氨酸阴离子呈两性离子形式。在晶体中，ASP阴离子通过N-H⋯O氢键相连，沿z轴方向形成一个双螺旋结构。这些螺旋通过ADE阳离子的O-H⋯O和N-H⋯O氢键相连，形成平行于xy平面的层。层中存在通道，被水分子占据，水分子通过O-H⋯O和N-H⋯O氢键与阴离子和阳离子相连。层内还存在C-H⋯O和C-H⋯π相互作用。
